摘　　要：IGBT驱动信号同步性是影响并联均流的关键因素。以采用并联扩容的1000 kW并联谐振感应加热电源为研究对象,设计了其IGBT驱动电路。首先通过DSP产生逆变桥的2路IGBT驱动信号;其次通过门电路实现驱动信号重叠时间设定,并利用驱动器将信号扩展为24路;最后通过2SP0115T2C0驱动模块及其外围电路实现了驱动信号的功率放大、隔离和IGBT的过流保护等功能。测试结果表明所设计的驱动电路信号同步性较好,信号间最大时延20 ns,具有较好的工程设计参考价值。Driving signal synchronization of IGBT module is the important factor to the current sharing of parallel connection.An IGBT driving circuit was designed for on the 1000 kW parallel resonant induction heating power source.First two IGBT drive signals of inverter bridge were generated by DSP.Second the overlapping time of signals was determined by gate circuit,and the signals were expanded to 24 channel by fast driving.Finally the power amplification and isolation of driving signal and overcurrent protection of IGBT were achieved by 2SP0115T2C0 driver module and its peripheral circuit.The designed driving circuit was indicated by actual test to have satisfactory synchronization of driving signal,to achieve a maximum inter-signal delay time of 20 ns,and thereby to be helpful in subsequent engineering design.
